The Asthika Samaj was set up as a place of public worship in Matunga, Mumbai, India, in the year 1923 by adorning the sacred hall with a portrait of Lord Sree Ramachandra. Eventually in 1953, with the blessings of His Holiness Jagadguru Sree Sankaracharya Swamigal of Kanchi Kamakoti Peetam, the Temple attained its full-fledged status by installation of idols of Lord Sree Ramachandra, Sitadevi, Lakshmanan and Hanuman in a specially created Garbhagriha.
The historical importance of the place can be traced from that the place, now has known as Matunga, was previously the abode of Mathangarishi who after performing the Mahayagnas on the banks of Pumpa acquired the coveted status of Maharishi. As a vestige of the ancient past, the banyan tree exists even to this date fulfilling the desires of thousands of devotees. The spiritual growth of the Samaj over the years coupled with the full support of the devotees enabled the installation of other deities such as Lord Karthikeyan (1965) Navagraha Idols (1967) Lord Kochu Guruvayoorappan (1974) and Swamy Ayyappan (1978).
